Our invention relates to oilburners of the type having a rotary head disposed centrally of a hearth and spraying oil to the outer periphery of the hearth where combustion takes place. The invention has for its principal objects to make all of the parts of such a device easily installable and removable and easily accessible ,for purposes of inspection and repair, to provide a better spray of fuel, to simplify the construction and lessen the cost thereof and to make the device small and compact. The invention consists in the o il burner and in the parts and combinations and arrangements of parts hereinafter described and claimed.- f

The main supporting frame of the burner construction comprises an annular wall member 1 provided withA lugs 2 that receive threaded leg members 3 that extend into threaded sleeves 4 in the tops of supporting cylinders 5 provided with suitable base members 6. Mounted on each threaded leg 3 isa line 6 6 lock nut 7 that rests on top of a sleeve 4. By

v this arrangement, the frame 1 can be leveled" and can be raised and lowered to desired posi tion andlocked in place.

`Secured to inwardly projecting supporting arms8 is a half` ring 9 disposed centrally be.

low the frame and with its axisvertical; and

a cooperating half ring 10 is secured to said arms 8 by means of screws 11, said rings `9 and 10 constituting a circular clamping device in which is received a cylindrical projecting nosin 12 of an electric motor housing 13. The oil distributor head 14 has a centralboss OIL BURNER shell is provided with openings 40 REI S ll La 15 that is provided with a conical bore 16 to fit the conical updper end 17 of the motor shaft 18, being secure by a screw 19 that is threaded into the end 17 of-said shaft 18. A fau or blower member 20 has an axial hole 21 in its body or disk portion 22 to receive an annular rib 23 on said boss 15, the inner margin of said disk portion 22 resting on top of said boss 15, encircling said rib 23 and being held by said screw 19. j

Mounted on top of said motor housing 13 is an annular headmember 24 that is provided with an upwardly and inwardly inclined bore 25. An oil supply pipe 26 is threaded into the lower end of said bore and a delivery tube 27 extends through said bore, projecting upwardly from the u per end of said head.

vThe upper end of sai tube is provided with an outwardly rebent tip 28 that overhangs a channel member 29 that is provided with an upwardly and outwardly sloping outer 'wall 30 terminating in a horizontal flange 31 whose outer edge portion 32 is rebent around a ange 33 at the periphery of said distributor head motor shaft 18, oil Vworks its way upwardly4 along the wall 30 into said recesses 35and said distributor'pipes 34 and is flung'outwardly by said pipes, fan blades being removed. that would interfere -with the spraying of oil. The motor head 24 is rovided with a drain tube 36 for any oil hat may *overflow into the headl from said channel member 29.

' The frame member 1 is provided around the lower portion of its inner periphery with a ledge 37 on which rests the lower edge portion o f a conical shell member 38 whose upper end has a projecting cylindrical portion 39 arranged in close proximity to the u per e Ue of the motor head member 24. aid

permittin passage ofl a1r. Disposed in said `conica shell member 38 is a cooperating conical shell member 41 with openings 42 correspondingv lZ'v,

to those 40 of the outer member 38. Said inner conical member 4l is provided with an operating handle 43 so that'it may be turned to bring the openings 40 and 42 into alinement with each other, wholly or in part,

Said inner conical member 41 is provided with lrecessed portions 45 around its lower periphery. Into each recess 45 extendsv a lever 46 that is mounted on a pin '47 in the frame 1 and the top of whose outer end portion is. engaged by a spring 48 mounted in saidframe 1. The pressure of said springs 48 forces the inner ends of said levers 46 upwardly against the inner conical member 41, thus holding it firmly in engagement with vthe outer member 38 with its lower edge spaced slightly above said ledge 37.

The frame member 1 is providedwith an annular groove 49 in which are received the edges of hearth supporting plates 50, the refractory hearth tile or brick being supported on said plates. Thus a hearth support oflarge area and ample strength is provided and may be installed with a minimum of effort. Thefraine member itselfmay be easily installed in the furnace, mounted at the correct height and adjusted to horizontal position.

Disposed adjacent to the burner is a transformer 51 for the electric ignition circuit. Said transformer 51 is provided with Z- shaped strips 52 providing a vertically ex tending slot 53 in which are received the hooked ends 54 of clamp members 55 that extend around one of said leg cylinders 5 and are secured by a bolt 56 and wing nut 57.

With the frame horizontal, the motor is easily mounted in the clamp member and may readily be adjusted for any desiredheiglit.

The frame being horizontal, it is im ssible for the motor to be clamped in any ut the necessary vertical position. As it is fnequently necessary to make adjustments of the oil and air discharge levels for proper combustion after the installation is conipleted, the importance of eliminating the necessity for a releveling procedure each time a vertical adjustment ismade is readily apparent. Heretofore it has been necessary to go through a laborious procedure lof cut and try adjustment of screws and locknuts until 'a bubble level indicated a proper horizontal discharge level for the oil. As leveling was necessary in all directions around the full circumference of the hearth circle the process was further complicated. As readjustment is usually done while'v the boiler is h ot it was very inconvenient to place and read the leveling device in its position upon the burner head within thecombustion chamber. With our arrangement after the initial leveling ofv With the motor in position it is a very' simple matter to place thecap and channelmember in place upon'the conical end of the motor shaft, position the fan upon the boss and secure all together by drawing down with the screw on the top of the shaft. .The

importance of this construction in conjunction with the clamping means is understood when it is'realized with what expediency the vital parts may be removed and replaced in` service. In actual practice it is possible to replace aburner motor and have the installation again in operation in less than' five minv A utes time. Fans and oil distributor heads usually require less than one minutefor replacement.

The adjustment of the air shutter is readily accomplished by moving the projecting handle member. The shutter remains fixed in any position it may be left, but a locking screw is provided to prevent accidental movement or tampering. The-inner edge of the air shutter is close enough to the head meir 1. ber so there is no substantial passage of air through the slit space there between. Thus the amount of air is easily controlled,'rattling' of the parts is prevented and the shutter may l be 'held securely in the desired position.`

Obviously numerous changes may be made without departing from the invention and we do not wish to be limited to the precise construction shown.
